Hi gang.. I have been idel forever - but I am back.
..
I have a Dell Optiplex 9020 Motherboard that I am installing into a Full Tower Case.
The Dell Motherboard uses a Dell Proprietary 8-Pin (Mini-Fit Jr style connector).
The Dell Connector Pinout s as follows:
Pin 1 - +12VDC - White Wire
Pin 2 - +12VDC - White Wire
Pin 3 - COM/GND - Black Wire
Pin 4 - PS_ON -Green Wire
Pin 5 - +12 SB - - Purple Wire
Pin 6 - COM/GND - Black Wire
Pin 7 - COM/GND - Black Wire
Pin 8 - PWE_OK - Grey Wire.
...
My problem is the Purple +5VSB (Pin 9 on ATX 20/24 Pin harness) wires on the ATX P.S. and the Purple +12 SB (pin 5) on the Dell 8-Pin Harness.
..
I need the control the +12 SB Pin with the +5VSB Pin.
..
So I found a simple Transistor 5V controlling 12 Volt Switch that was posted by BradtheRAD on this forum (but not discussing the Dell,Power Supply issue).
The Circuit is here:
..
My question is will this work to control the +12 SB using the ATX +5VSB? ?? Both signals do the same thing it is just that the ATX standard uses a +5V standarsd and Mchael Dell' people cose to use a +12V voltage reference. Little current is involved.
